Airtac MTD Multi-position Locking Cylinder MTD20X15
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD20X15 is a genuine MD multi-mount cylinder (single acting, pull type), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 92.3 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD20X15
The MTD20X15 is an AirTAC multi-mount cylinder: a compact square-body cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with identical units to save space. This version has a 20 mm bore with a 15 mm stroke and is single acting, pull type: air pressure retracts the rod and the internal spring returns it. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), operates from -20 to 70 C, reaches speeds of 50-500 mm/s, and is cushioned by an elastic bumper. Because it carries no magnet code, this SKU is supplied without a magnetic piston for switch sensing.
This is a genuine AirTAC part from the MD multi-mount family, the standard series where the rod is free to rotate; if you need the rod or plate held against rotation, choose the MK no-rotating series instead. The body has slots for magnetic switches, but this non-magnet SKU will not trigger them. Construction is typically aluminium alloy body, covers and piston with a stainless or S45C rod and NBR seals. We will confirm exact dimensions and sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Choose the bore for the thrust your job needs; for this pull-type single acting variant, confirm the pull-side thrust from the datasheet, noting that the pull side delivers less force than the push side of a comparable push-type cylinder. Pick the acting type deliberately: double acting (MD), single acting push (MSD), single acting pull (MTD, this model), double rod (MDD) or adjustable stroke (MDJ). This 15 mm stroke sits within the single acting limit of 20 mm; the short cover means very long strokes are not offered, so avoid specifying more travel than the series supports. Magnet is added only with the S suffix (MTD20X15S); this SKU has none. Port thread is PT as standard, or G with the G suffix, both M5x0.8 on this bore. Side-load capability is not stated here; check it with us against the datasheet.
Applications
Spring-extend conveyor stopper
Mounted through the top or side face of the compact body, the cylinder holds a stopper blade in the path of small items on a light conveyor line; air pressure pulls it clear and the spring returns it to block, a fail-safe pause point on a 15 mm travel stop.
Small-parts clamp fixture
Bolted side by side along a machining or assembly jig, the 20 mm bore unit clamps small brackets or housings into a nest; the single acting pull design releases the part when air is applied, keeping the clamp engaged whenever air pressure is lost.
Jig positioning pin
Fixed from the bottom face under a welding or inspection jig, the short-stroke rod drives a positioning pin into a bushed hole to index the workpiece; the 15 mm stroke suits pin-in / pin-out motion where space under the jig plate is tight.
FAQ
What does the MTD20X15 model code mean?
MTD is the single acting, pull type variant of the AirTAC MD multi-mount family: air pressure retracts the rod and a spring returns it. The 20 is the bore in mm, 15 is the stroke in mm, there is no S suffix so no magnet is fitted, and there is no G suffix so the ports are PT thread, M5x0.8 on this bore. For a built-in magnet, order MTD20X15S.
How many ways can I mount this cylinder, and are there stroke limits?
The square body can be fixed from 6 directions (front, back, left, right, top and bottom) and units can sit side by side to save space. Note that single acting versions of this series are limited to strokes up to 20 mm because of the short cover, so this 15 mm stroke is near the top of the range. For side-load figures and exact per-stroke dimensions, confirm from the datasheet.
